N149 Practical Salt Tectonics
N149 Practical Salt Tectonics
This class discusses the origin and distribution of salt and provides intense instruction on the essential elements of salt mechanics, diapirism, structural styles of salt deformation and salt-sediment interaction. It comprises lectures and exercises involving interpretation of seismic data from basins around the world.
A four-day course emphasising the geometry and evolution of salt structures and their impact on petroleum systems. It consists of lectures, discussion and exercises.
Participants will learn to:
2. Salt basins
3. Exercise 1 – Salt and presalt, South Atlantic
5. Diapir Initiation
6. Exercise 2 - Evacuation Geometries
7. Diapir Reactivation
8. Exercise 3 - Diapir Styles
9. Passive Diapirs
10. Exercise 4 - Halokinetic sequences
11. Allochthonous salt
12. Exercise 5 - GoM Allochthonous salt
13. Salt in thick-skinned extension
14. Exercise 6 - Central North Sea
15. Salt in convergent-margin foldbelts
16. Salt on passive margins
17. Exercise 7 - Espirito Sant Basin (proximal)
18. Salt on passive margins (Cont.)
19. Exercise 8 - Espirito Santo Basin (distal)
20. Petroleum Systems Implications
21. Interpretation guidelines
Exploration and development geologists and geophysicists working in salt basins around the world.
A basic working knowledge of structural geology (as offered in N016, N090 or N220) and seismic interpretation (as offered in N085 or N040) is required.
Potential attendees should note that salt tectonics courses N071, N149 and N232 have similar classroom content taught by Mark Rowan. The principal differences are: N071 - US-based classroom course with an emphasis on Gulf of Mexico tectonic styles and geophysical aspects of salt systems, less information on salt in thick-skinned tectonic regimes. N149 - EU-based classroom course, equal treatment of salt tectonic styles around the world including in fold and thrust belts. N232 - classroom content as for M149 but includes 4 days in the field in the Basque-Cantabrian fold belt with associated regional geological context and seismic exercise based on local data.
